util_t_param_estimate {TidyDensity}

Estimate t Distribution Parameters

Description

Estimate t Distribution Parameters

Usage

util_t_param_estimate(.x, .auto_gen_empirical = TRUE)

Arguments

.x

The vector of data to be passed to the function, where the data comes from the rt() function.

.auto_gen_empirical

This is a boolean value of TRUE/FALSE with default set to TRUE. This will automatically create the tidy_empirical() output for the .x parameter and use the tidy_combine_distributions(). The user can then plot out the data using ⁠$combined_data_tbl⁠ from the function output.

Details

This function will attempt to estimate the t distribution parameters given some vector of values produced by rt(). The estimation method uses both method of moments and maximum likelihood estimation.

Value

A tibble/list
